Swingingly mountedon the lower'forward brace 3 is;a platen 21. 'I-Iinges 19a're used" for this purpose It-Wil'l be understood that a plurality of; platens and associated parts is to be used, but that only one will be (le scribed herein, each of them being the same. Each platen 21 is hingeddirectly behi ndan opening 23 in the table 1, sai'd opening 23 accommodating the passage of a bin25;

' Each" platen 21' co npri se'sa T relatively flat b'ottomz27:haVingsideward, upwardly formed chanrfels 29; an dal'ateralstdp 31.

It will be seen that the rolled portion 39 (Fig. 6) function, not only as a brace for making more rigid the front 35, but also act as a longitudinal brace or spacer between the sides 41.

It will also be noted from Fig. 5 that the false bottom 53 is of such a shape, when taken in connection with the back 13 of the bin 25, that there is engagement with the angle iron 31 when the bin is in a predetermined forward position. This position is predeter mined by the point at whch an overhang of the load in the bin will tilt the platen 21 upwardly automatically, that is, when the bin is pulled forwardly up the incline of the platen.

It will be appreciated that the rollers or wheels 33 are positioned so that the forward ones of the same do not run off of the platen 21 in the limiting forward position of the bin. The rearward set of rollers 33 are positioned with this same consideration in mind for the rearward limiting positioning of the bin. Figs. 1 and 5 show how square pieces of ma terial 55 are used between the bin and the rollers 33 for making the mounting of the rollers more rigid.

The operation is as follows:

The platen 21 rests against the bottom 9 of the counter or table 1. This positioning gives the platen a back slope and the bin 25 consequently rests in its rearward position shown in Fig. 1 with the flanges 37, 49 thereof resting against the sides of the opening 23. Thus the rearward positioning of the bin is limited and the opening 23 at the same time substantially sealed against entry of foreign material.

To open the bin the handle 57 thereof is grasped and drawn forwardly. This causes the bin to ascend the incline formed by the platen 21, until the center of gravity of the material in the bin causes it to over-center and lift the platen as shown in Fig. 2. Thereafter the lower flange of the back 13 strikes the stop 31 (see Fig. 5) and the bin tilts upwardly. The platen continues to tilt upwardly until the upper edge 59 of the bin strikes one of the longitudinal angle irons 3 or other suitable part on the table 1." Thus the positioning of the bin is limited to that shown in Fig. 3 for purposes of taking material therefrom and placing material therein.

When it is desired again to close the bin, it is only necessary to push the handle 57, whereupon the platen 21 rotates clockwise to the Fig. 2 position. A slight further pressure causes the bin 25 to slide inwardly on the platen and causes gravity to throw the platen down into the Fig. 1 position. Thus it will be seen that during each event, part of the motion is effected automatically. During opening, the latter half of the movement is effected automatically by the overcentering action; and during closing the latter half of the movement is eli'ected by the action of the weight of the bin sliding down the incline of the platen.

Reference to Figs. 1 to 3 shows that the bracing angle iron 17 is so positioned longitudinally that it is directly beneath the point of contact of the rear end of the platen 21 with the bottom 9 of the table 1. Thus the load of the bin is properly supported.

One of the advantages of the present invention is that the rollers 33 are attached to the bin itself and thus the rolling or coasting action of the bin always take places along the same line in respect to the platen. Also, the platen always moves in a predetermined manner with respect to the table 1. Thus the action which will be effected in view of the load within the bin is about the same every time that the bin is opened. In constructions wherein a bin has a pivoting action at any one of various points, depending upon the load therein, the action is awkward to the operator, because he does not known just what action will occur, the action being variable to an extreme degree.

Furthermore, the separation of the coasting action from the turning action, that is, separating the hinge 19 from the rollers 33 effects a much easier method for swinging the bin. The fact that the hinging point is not movable is advantageous in effecting a rigid and dependably operable structure.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in carrying out the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim:

1. In a device of the class described, a support having an opening, a bin slidable in said opening to assume open and closed positions relative to said opening and said support, a swingable platen, a pivot for said platen, said pivot being positioned nearer said opening than the center of gravity of said bin when in closed position relative to said opening, means slidably oining the bin to the platen, whereby the bin may be moved between open and closed position, and the center of gravity thereof thereby shifted from one side of said pivot to the other.

2. In a device of the class described, a support having an opening, a fixed hinge behind said opening, a platen swingably supported at its forward end by said hinge and resting with a slope normally directed downwardly and rearwardly from the opening, a bin, means for slidably supporting the bin on said platen, said bin being adapted to be withdrawn from the opening over said hinge, said platen being then automatically tilted to slope downwardly toward the opening for permitting descent of the bin thereover.

3. In a device of the class described, a support having an opening, a fixed hinge behind said opening, a platen swingably supported at its forward end by said hinge and resting with a slope normally directed downwardly and away from the opening, a bin, means for slidably supporting the bin on said platen, said bin being adapted to be withdrawn from the opening over said hinge, said platen being swingable to slope downwardly toward the opening for permitting said bin to be moved further therefrom, said slidable means comprising a plurality of rollers fastened to the bin and channels on the platen surrounding a plurality of said rollers.

4. In a device of the class described, a support including an opening, a bin slidable through said opening, a hinge back of the opening, said hinge being fixed, a platen swingable on said hinge, rollers fastened to said bin movable on said platen, means engageable with the edge of said opening for limiting the rearward movement of the bin on the platen, means on the platen limiting the forward movement of the bin thereon, the swinging movement of the bin and platen provided by the said pivot being limited by engagement of the top of the bin with the upper part of said support. v

5. In a device of the class described, a support, a platen hinged to the support, a bin, rollers on the bin rolling on said platen, a bottom for the bin, a downwardly extending flange formed by the sides of said bin and said bottom, and a stop on the platen adapted to interiorly engage said flange below said bottom for limiting the forward movement of the bin on the platen.

In testimony whereof, I have signed my name to this specification this 20th day of January, 1930.
